Hey guys, I just bought an 09 Frontier with 52k miles and just started reading a lot about the radiators having issues in 05+ Frontiers that are causing transmission failure. My question is what years was this a problem on? Was it fixed by 09? Before I bought the truck I did a lot of research and did not see many people reporting these issues in 09-10 but a lot of people reporting it in early years. I also had the dealer look at the fluids prior to buying and it seemed fine. Just curious at what mileage this happens and what actually causes the issue. Any insight is greatly appreciated?
